NOZZLE.

Specification of Letters Patent.

' Patented May 4, 1909.

Be it known that-I, WILLIAM G. HUGHES, a citizenof the United States,residing at Los in the county of Los Angeles and Stateof California,have invented new and useful Improvements in Nozzles, of which thefollowing is a s ecification.

My invention re ates to a nozzle adapted to sprinkling purposes and therime object thereof is to rovide a nozzle w ich will adjust itself toarge variations of pressure. and volume sothat it will throw a finespray uniformly over a large area under either a light or heavy ressure.

A furt er object is to provide a nozzle which will evenly distribute afine. spray over a large area and which will not become clogged by anyforeign matter in the water fed to the same. I

A further object .is to provide a nozzle in which the wearing parts maybe readily re placed by any new parts when worn out.

I accomplish these objects by means of the device described herein andillustrated in the accompanying drawings, in which Figure 1. is a frontelevation of my improved -nozzle. Fig. 2. is a longitudinal Fig. 3.- isa perspective detail of the bottom end of the nozzle tube showing thenotches therein. Fi 4.- is a section similar to Fig. 2 of amodi fiedform of nozzle. 1

Referring to the drawings, 5 designates a base, preferably made of castmetal and provided withprojecting base lugs 6 which are adapted toimpart stability in a direction at right angles to the hose, (notshown). The hose, which screws into threaded opening -7, impartsstability to the nozzle in the direc tion along the hose and thereby,with the assistance of base lugs 6, prevents it from tipping from itsvertical position. 7

Base 5 is rovided with a passage 8 which leads fromose opening 7horizontally and then upwardly to nozzle tube 9 into which the water isdischarged from the hose. Tube 9 is preferably secured to base 5 bsolder and is provided with a preferably cone shaped stopper. 10 havinga-downwardly ex-r tendin stem 11 to the lower end of which is hooke theup er end of a rod 12. The lower end of ro 12 passes throu h adetachable bar 13 which fits across the lower end of tube 9 in notches14 cut in the tube for that purpose. A compression spring 15 surroundsthe end of rod 12 below bar 13 exert end of the rod. Spring 15 isconsiderably smaller in diameter than the passageway so as to leave asufiicient space around it to provide for the passagetherethroughof'foreign substances. In the normal position of stopper 10,spring 15 is in compression so as to old stopper 10 on its seat againsta considerable pressure of water underneath the same. I

In Fig. 4 I have shown a modified form of nozzle in which a tensionspring is utilized in place of the compression spring and ro( thereforin the first form. In this form the upppr end of the spring issecured'directly .to t e stopper and the lower end to crossbar 13.

mg a downward pressure on a washer on the In the operation of my nozzle,the water pressure in tube 9 understopper 10 will raise the same until asufiicient opening has been created between the'tube and the stopper toallow the amount of water being supplied to the nozzle to flow outthrough the opening. In this manner the water is spread into a coneshaped sheet until it strikes a shoulder 16 where the sheet is broken upinto a line spray, part of the water entering the out below the shoulderand rebounding therefromto strike the body; of water in the cone shapedsheet and brea it up into small particles, which rebound in everydirection so that the resultant spray is evenly distributed within theradius of, operation of the nozzle.

The above explained action will take place with a large or small amountof water as the stopper will rise off of its seat on the top of thetube, just enough to allow the. amount of water fed to the nozzle toescape. The spraying action will take lace with a small amount of-wateras we as with a large amount of water as the spring holds the stopperdown until a sufiicient ressure has been raised inside the nozzle toorce the water into a spray. On account of the universal connectionformed by the hook and. eye between rod 12 and stopper 10, it will beobserved that the stopper is permitted, to be moved freely by t aroundit. If 1 the stop er were rigidly mounted in a transverse ireotion it isseen that especial care'would have to be taken .to make it perfectlyconcentric with the tube so that t e water would flow equally on allsides of it. With the presentconstruetion e water passing being Theassageways of my nozzle are all sullicient y large to insure the passagetherethrough of any growth whie 1 often occurs in water systems andwhich is the source of I constant clogging of all spraying nozzles whichemploy small passagewa s. Should a stone or other solid substance odgein the 1 nozzle it will be forced upwardly to the stopper whenthe-stopper will rise enough to ermit the escape of such solid.substance.-

Thus it will be seen that nothing except a .very large stone or the likecan clog my nozzle, and any substance of that size is prevented -fromentering water systems by filters or similar devices.

Having described my invention what I claim as new and desire to secureby Letters Patent is:

1. A sprinkler nozzle, comprising a tube adapted to beconnected atone'end' to a source of water supply, a stopper for the discharge end ofsaid tube, and resiliently actuated means to hold said sto )per inplace, said means being univcrsa y connected to said stopper.

2. A sprinkler nozzle, comprising a tube adapted to be connected at oneend to a source of water supply, a conical stopper for the discharge endof said tube, said stopper being provided with an annular shoulderthereon, and resiliently actuated. means to hold said stopper in place,said means being universally COIIIIGCtCL to said stopper.

A sprinkler nozzle, comprising a tube adapted to be connected at one endto a source of. water supply, a conical stopper for the discharge end ofsaid tube, said stopper being provided with an annular groove thereinbeyond the end of the tube, and a spring actuated rod mounted in saidtube, said rod being universally connected to said stopper.

4. A sprinkler nozzle comprising a vertically disposed tube, a base forsaidtube, said base adapted to be eonncctedto a source of water supplyand being provided with a water passage leading to the base of saidtube, an inverted conical stopper adapted to close the upper end of saidtube, said stopper having an annular groove above the upper end of saidtube, a bar across the lower end of said tube, a rod pivotally attachedto said stopper and passing down-.

wardly through said bar, and a compressi n spring around said rod belowsaid bar, said spring being adapted to force said-rod downwardly.

5. A sprinkler nozzle, comprising a tube adapted to be connected at oneend to a source ol' water supply, a stopper for the discharge end olsaid tube, and a spring actuated rod mounted in said tube, said rod.

being universally connected to said stopper. In witness that I claim theforegoing l have hereunto subscribed my name this 26th day ol June,1907.
